I am new to scripting, would like to have a script that tests whether a directory exists on remote host & display the message accordingly. The remote hostname can be provided by means of file containing list of hostnames. Can use rsh for connecting to remote host.I tried with couple of scripts by searching google but didn't get desired result. Please help me, below is my efforts, $file contains list of hostnames.

I need to write a shell script which can ready content of the folder and place files on remote FTP server.

The files will be generated by MySQL every hour.
How do I obtain information about the running x-server from a remote shell session? I want to know things like resolution, color depth, etc. My xorg.conf is basically empty. The only thing I can think of doing is to read the Xorg.0.log file which seems inefficient.
I thought that 'xrandr' displayed some text output but that behavior has changed (?). It seems to require an X display. Is there another way? Something I could incorporate into a shell script? (This is Fedora but that shouldn't really matter)

I have two linux servers, they are backup together.
1. Server 1 have 3 files with name: file1, file2, file3 in the path: /etc/sysconfig/network-script/.
2. Server 2 have 3 files with name and path are the same as server 1.
- How to make a script to copy 3 files at server1 to overwrite on server2. But before overwrite, this script will check and compare the last modified date of these 3 files(on server1 and server2). if the modified date of file1, file2 or file3 on server1 is newer than 3 files on server2 then overwrite process will do, if not, will do nothing.
- see my script as below: it works find now but just overwrite. not check last modified date.
I've written a shell script that among other things, restarts network services. As such, I'd like to keep those who are remoting in via putty, etc. from executing the script. Is there a way to detect this and restrict running the script (by adding additional coding in the script) that disallows running it from unless you are logged in directly to the machine? It's written in bash.
I have an Ubuntu server in which a file is dumped every hour and a new file for the next hour and the process continues. If there is any problem due to which the creation of file stops then empty files are created every minute till the process is killed & started again. I need help to make a shell script to check if the empty files are being created and then kill the process and start it again.It would be a great help if anyone can help me regarding this.
I am using debian testing on my office pc, but i need to access it's desktop from time to time. So i need No machine/teamviewer software that can provide me with possibility to interact my desktop. The problem is, that i want to run shadowed session type, because teamviewer is not good for me. So, when i run no machine in shadowed mode, it crashes with message "The connection with remote server was shut down, please check your network settings and try again." The log is here:
I am trying to write some small script file that will check if a USB stick is connected to my pc or not. I can't seem to get it to work, but I am sure it is a very simple fix.
I am running on Fedora core 10.Can anyone help me figure out what the problem is?If I run these lines through console it works fine (meaning, I type the commands in this file straight in the command line/console).
I have a file that's supposed to be growing in size 24/7. I want to check every 10 minutes via cron that it's actually growing. If not, send an email. Does anyone know how to write a script to do that?
I'm playing a game through wine (fullscreen), when I alt-tab back to my ubuntu desktop, the resolution doesn't change back, but stays at the game resolution.I'm currently using a shellscript that changes the resolution back to my origional resolution (using xrandr -s 0)
Is it possible to check which window has focus using a shellscript.If the game doesn't have focus change resolution to my origional resolution.
how i have a machine installed Red Hat Enterprise Linux Server release 5.1 with 2 modem (usb & com port) still i want to configure RAS server so some pple able to connect my server and send me some files.
I have developed a small website using jspx pages.Now i want to host the website to a server which is a linux machine.The linux machine which i m referring to is already hosting some web pages(jspx) through a web server Which is running at port 8888.My first question would be "How would i check which web server is installed in the server?"Due to my little knowledge about linux machine .I have copied some simple html pages to /var/ www/ html location. The pages are getting accessed correctly on port number 80.But how would i go about hosting jspx pages.
I'm looking for an easy way to check if some server is down, and then act upon it. This check needs to be done from the backup-server. So if the backup-server thinks the production server is down, then in some bash script I want to execute a rule.
My question: what is an easy way to check another server ? 1. I know about Nagios. It's great, but to large to use here. 2. I could ping the server, put a ping that fails does not necessarily mean the server is down.
I am a novice to the shell script. In my system from db server the log files are enerating with the name log1.txt,log2.txt..... It is capable of keeping 10 files at a time in dir called /db/sis/log1.txt. I want to copy the log1.txt to another directory when ever it generating by attaching the time stamp to it for the back-up purpose. this files will be there for a period of 24 hours. after that the back-up dir should be cleared and it start copying again the fresh file from the same dir.
HP's apparently all but useless Linux site suggests that their hplip drivers give you that capability. However, it also seems to expect that I will be running a GUI to use their tools.
My CP-1215 is attached to my server which doesn't have a GUI installed.
Previously I'd been using the open source CUPS driver, which seemed to work pretty well. However, I recently ran low on one colour of toner which messed up the printing. The toner-out lights on the printer never cam one, so replacing the toner cartridge was not the first thing I tried to fix it.
I've just installed the hplip / hp-plugin driver which also seems to be working. However, the CUPS web interface doesn't allow me to retrieve the toner status.
Has anyone had any luck retrieving the toner levels from an HP colour laserjet printer?
I am implementing an automated backup scheme so I created a shell script which first creates SQL dumps for all MySQL databases, then retrieves all websites from the /var/www directory of a remote server. The latter is working as I am using rsync to get the remote files.However, the MySQL dumps being retrieved are the ones from the local server which is not what I want. I want to get the SQL dumps from the remote server as well.I have a tunnel between the local and remote server which I can connect to without using any password (I added the public key to the authorized_hosts), so I tried to add the following code to the script:
I then attempted to retrieve the SQL dumps and exited from the remote server. However this does not work as I still have to enter exit manually in the terminal for the SQL dumps to be retrieved from the remote host. I don't know why this is happening. This is what the script is trying to do:
//connect to remote server ssh firstname.lastname@example.org //retrieve SQL dumps
Is there a way to connect to the remote host AND run the script's code on THAT remote host?
